Well, I've done a lot of testing for MIT on those libraries, and MIT
kerberos libs still are not as fast as the Heimdal ones. There is also the
added bit now that you would have to disable the mutex locks in Cyrus-SASL
for MIT builds to even test this. In addition, to get any sort of speed
from the MIT libraries, you have to disable the replay cache.

"These censorship operations against schools and libraries are stronger
than ever in the present religio-political climate. They often focus on
fantasy and sf books, which foster that deadly enemy to bigotry and blind
faith, the imagination." -- Ursula K. Le Guin
